Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a convenient cultivation aid mainly used when sowing plant seeds.

Conventionally, in various production fields such as vegetable gardening and floriculture, where seedlings are obtained by sowing seeds, seedlings must be transplanted over and over again in order to obtain good seedlings with fully developed lateral roots and fine roots. However, this transplanting process not only forced the grower to do very hard labor, but also caused a great deal of damage to the plant during the process, and did not necessarily have a positive effect on the plant. .

The present invention has been made in view of the above-mentioned problems, and is mainly used at the time of sowing to successfully remove tap roots that rapidly grow almost vertically downward and roots that grow without forming a large angle with the tap roots using a ligature tool. When the seedling is introduced into the ligated hole and grows to a certain size, the development of the main root and the roots that grow without forming a large angle with the main root is suppressed, and these are replaced by lateral roots and other roots. Natural development of rootlets from. The purpose of this invention is to provide a cultivation aid that promotes development and allows extremely healthy plants, which are not found in the prior art, to be obtained without transplanting even once. The cultivation aid of the present invention is a technology related to the cultivation aid described in Patent Application No. 210643 filed in 1982 by the same applicant, the specification of which is titled "Cultivation Aid."

The cultivation aid of the present invention will be described in detail below using examples shown in the drawings.

That is, the cultivation aid of the present invention is a cylinder having the property of deteriorating and disintegrating over time under the germination conditions of plant seeds, or
A root guiding cylinder (1), which is a bottomed or bottomless molded product having a circular or polygonal lattice shape, has a large number of ligation holes (3) at one end with a smaller cross-sectional area. It is a device in which a ligating tool (2) is fitted or pasted.

The product is obtained by filling the guiding cylinder (1) with culture soil (6), etc. as necessary, and sowing plant seeds (7) therein.

Example 1 ○ A large number of ligated small holes are formed inside the lower end of a cylinder or rattura-shaped guide cylinder (1) with a bottom or without a bottom, which is formed by adding humus, etc., as the main raw material and occasionally adding fertilizer, etc. (3) A cultivation aid formed by fitting and fixing a flat plate-shaped ligature (2).

○A cultivation aid similar to the above-mentioned one, in which a large number of small holes (4) are provided in the guiding cylinder (1) mainly in the portion where the lateral roots are expected to penetrate.

A ligature tool having a large number of small ligation holes (
2) Embed the device almost vertically into the soil of the field to about 80% of its total length with the end facing down, and then pour the culture soil from the open top end to the same height as the ground surface. When the seeds were added to the soil and then sown several seeds on top, covered with soil and watered, these seeds germinated after a few days and showed very good growth.

During the growth process, we dug up the plant body and observed the underground part, and found that the tap root and the roots that had grown without forming a large angle with the tap root were successfully introduced into the ligating hole (3) of the ligating tool (2) and ligated. Although growth is restricted below the ligation of the main root and the roots that have grown without forming a large angle with the main root, it still survives, whereas above the ligation the lateral roots and fine roots from there become extremely vigorous. It was developing evenly. Flowering and fruiting were also vigorous.

Example 2 A large number of shallow bowl-shaped ligature holes (3) are provided inside the lower end of a bottomed or bottomless guiding cylinder (1) in the shape of a cylinder or lappa made of humus or the like as the main raw material. Ligation tool (2)
A small amount of fertilizer, etc. (11) is mixed in about 80% of the total length on the inner bottom plate (8) or lower cover piece (10) of the guide cylinder (1) of the cultivation aid, which is made by fitting etc. A cultivation aid filled with soil (6), on which several seeds are sown, covered with soil, and sealed with an upper cover piece (9).

○ A cultivation aid similar to the above, which is formed by providing a large number of small thin-walled parts (5) mainly in the part where the lateral roots are expected to pass through the guide cylinder (1).

A ligature tool having a large number of small ligation holes (
When the seeds (2) were inserted almost vertically into the soil of a field up to about 80% of their total length with the end facing down and watered, these seeds germinated after a few days and showed very good growth. Ta. When we dug up the plant during its growth process and observed the underground part, we found that the roots that had grown without forming a large angle with the roots were successfully tied with a ligature (2).
It is introduced into the small ligation hole (3) and ligated, and the growth is suppressed below the ligation of the main root and the roots that have grown without forming a large angle with this, but still survive.
On the other hand, lateral roots and fine roots from them were developing extremely vigorously above the ligation. Flowering and fruiting were also vigorous.

Example 3 Two corrugated sheets (12) formed from humus etc. as the main raw material and having grooves at equal intervals are stacked together with the grooves inside, and the corrugated sheets (12) are placed between the corrugated sheets (12). A cultivation aid equipped with a ligating tool (2) formed with a cylindrical part (13) and provided with a large number of ligating holes (3) inside each lower end of the cylindrical part (13).

The ligating tool (2) having a large number of ligating holes is the one in which seeds are clamped or attached within the cylindrical part (13) of the cultivation aid of this configuration without using culture soil. When the seeds were buried almost vertically in the field with their edges facing down and watered, the seeds germinated within a few days and showed very good growth. During the growth process, we dug up the plant body and observed the underground part, and found that the tap root and the roots that had grown without making a large angle with it were successfully ligated (2).
) is introduced into the ligation hole (3) and ligated, and the growth of the main root and the roots that have grown without forming a large angle with the ligation are suppressed but still survive, and instead the ligation Above the section, lateral roots and fine roots from them were extremely vigorously developed. Flowering and fruiting were also vigorous. In the case of this embodiment, it is possible to fold, roll up, etc., and not only requires less storage space, but also fully exhibits its effects when planted in large quantities, and is particularly suitable for commercial cultivation.

The bottomed or bottomless guide cylinder (1) used in the cultivation aid of the present invention is molded using humus, natural woven fiber waste, water-soluble resin, etc. as the main raw material, as described in the embodiments. After seed germination, the taproot that rapidly grows almost vertically downward and the roots that grow without forming a large angle with the taproot can be successfully removed from the ligation hole (3) in which the lower ligature (2) is used. After introduction into the main root, it gradually deteriorates and disintegrates and acts as a soil conditioner, etc. It guides the elongation of lateral roots and fine roots from there, which are generated from the ligated part of the main root and the roots that have grown without forming a large angle with the main root. It is well promoted. In addition, the cultivation aid of the present invention, which contains the culturing soil (6) and plant seeds (7) in the guide cylinder (1), often has a bottom, or the guide cylinder (1) is often bottomed. At the top and bottom opening ends of 1), attach the top cover piece (9) and the bottom cover piece (
10) is installed, but in these cases, it is desirable that the bottom plate (2) and each lid piece, like the guide cylinder (1), easily deteriorate and disintegrate under plant seed germination conditions; In particular, the bottom plate portion (8) and the lower lid piece (10) are designed to prevent at least the roots, including the main root, from extending outside the guiding cylinder (1) without forming a large angle with the main root. Must not be.

A ligature tool (3) having a large number of ligature holes (3) which is used in the cultivation aid of the present invention and best characterizes it is
Regarding 2), ceramics are generally selected as the material, but other materials can also be used that are physically and chemically stable and that support the enlargement of the taproot and roots that have grown without forming a large angle with it. Anything that can withstand destructive forces can be used as plastics.
Metals, glass, etc., or composites thereof, etc. can also be used. For example, by molding and sintering powdered materials such as lava rock and slag, an extremely excellent porous ligating tool having moderately uneven edges on the ligating edge is obtained. In addition, the above ligature tool (
2) Regarding the ligation holes (3), which are provided in large numbers and penetrate from the upper surface to the lower surface, and the one in the center is often larger in diameter than the others, their general planar shape is circular. , ellipses, polygons (of course including star shapes, etc.), or composite shapes of these, and according to their cross sections, they often have a shape cut from one or both sides. This is used as a guiding slope (15), and the ligation edge thereof is often wedge-shaped.

According to the cultivation aid of the present invention, after seeds germinate, the tap root that rapidly elongates and the roots that elongate without making a large angle with the main root descend along the inner wall of the guiding cylinder, and are finally applied to the ligating tool in large numbers. The ligature passes through a certain ligation hole and continues to extend out of the cylinder, and the ligature tool has many ligation holes (
3) can be reliably introduced.

Then, the main root that enlarges over time in the ligation hole of the ligation tool, and the roots that grow without making a large angle with the main root, are relatively tightened by the ligation edge of the ligation hole, and the roots in this part become tightened. The transfer of nutrients, water, etc. into the plant body is significantly inhibited, and as a result, the development of the main root and the roots that have grown without making a large angle with it, below the ligation, is suppressed, and at the same time, the main root is inhibited. The development of the roots and the roots that have extended without making a large angle with them beyond the ligation area is promoted, and lateral roots and fine roots are evenly generated from this area in an almost horizontal direction.
The degree of dependence on the taproot below the ligature in the above-ground part of the plant and the roots that grew without forming a large angle with it gradually decreased, and gradually the dependence on the taproot above the ligature and the roots that grew without making a large angle with it gradually decreased. Lateral roots develop from the roots and then the roots develop into fine roots. By using the cultivation aid of the present invention, growers will not only be freed from the task of repeatedly transplanting young seedlings, which has been commonly done in the past, but also allow the plant to be grown in the same field from sowing to harvest. Since it will be cultivated in one place, it will be able to escape the repeated heavy blows of transplanting, and will naturally grow the lateral roots and fine roots from there above the ligated part of the main root and the roots that have grown without forming a large angle with it. It is possible to generate and develop a sufficient rhizosphere, which increases resistance to pests and diseases, and increases yield. Furthermore, with the cultivation aid of the present invention, fertilization is effective for healthy plants that have reasonably well developed lateral roots and fine roots from them beyond the ligature of the main root and the roots that have extended without forming a large angle with the main root. This is remarkable, and the fact that it exhibits properties suitable for fertilization management, and indeed for intensive cultivation, far exceeds that obtained using conventional techniques. The cultivation aid of the present invention can be effectively used in production fields such as vegetable gardening and floriculture where seedlings are obtained by sowing seeds. The cultivation aid of the present invention, in which the guiding cylinder is filled with culture soil and seeding is completed, is extremely easy to use, so it is convenient even for beginners and may be commercially available.
